PDG21M0100TFFJ - 100 Amp Circuit Breaker

PDG21M0100TFFJ - 100 Amp Circuit Breaker

The Eaton PDG21M0100TFFJ is a 100-amp, 1-pole molded case circuit breaker from the Power Defense line. Built on the Frame 2 platform, it has an interrupting rating of 65 kA at 277 VAC, making it a good fit for compatible commercial and industrial electrical systems that require higher fault-current protection. This breaker uses a fixed-trip design, so there are no adjustable trip settings to configure in the field. It also comes with line and load lugs, giving installers the connection points needed for the specified application. At approximately 6 inches high, 1.38 inches wide, and 3.5 inches deep, the PDG21M0100TFFJ offers a compact footprint without giving up its 100A rating or 65kA interrupting capacity. If you're replacing an existing breaker, the catalog number is a great place to start. However, it's still worth checking the poles, amperage, voltage, A.I.C. rating, dimensions, and connection requirements against your equipment before installation.

Key Features and Benefits

• 100A rating for compatible commercial and industrial electrical applications.
• Single-pole design for systems requiring a 1-pole breaker.
• A 65 kA A.I.C. rating at 277 VAC provides high fault-current interrupting capability.
• Fixed trip keeps the protection setup simple, with no field-adjustable trip settings.
• Frame 2 construction provides capable circuit protection in a relatively compact size.
• Line and load lugs included for the required electrical connections.
• Compact 6.0" H x 1.38" W x 3.5" D dimensions can be useful where available equipment space matters.

Material Compliance and Certifications

• The PDG21M0100TFFJ belongs to Eaton's globally rated Power Defense molded case circuit breaker family. Certifications, listings, and material compliance requirements may differ depending on the specific breaker configuration and application. Check the breaker nameplate and current manufacturer documentation when a project requires confirmation of a particular certification, listing, or compliance standard.
  

Where It Works Best

• The PDG21M0100TFFJ makes sense for commercial and industrial electrical applications that require a 100A, 1-pole molded-case circuit breaker rated at 65kA at 277 VAC. It can be a practical choice for equipment replacement, maintenance work, electrical distribution systems, and other compatible installations where a fixed-trip Frame 2 breaker is specified.
  
• Replacing an existing circuit breaker? Don't rely on amperage alone. A breaker may look similar and still have the wrong electrical or physical characteristics. Check the PDG21M0100TFFJ part number, pole count, amperage, voltage, interrupting rating, trip type, dimensions, and lug configuration against the requirements of your equipment. A few minutes spent confirming those details can save a lot of trouble later.
